The short version: get the DeWalt DCS565 — a brushless 6-1/2" saw built blade-left (right-hander's sightline), with an electric brake, on the same DeWalt 20V MAX battery as the drill and impact driver we recommend. Want the cheapest full-size way in? The Ryobi ONE+ HP 7-1/4". Want pro-grade? The Milwaukee M18 FUEL 6-1/2" (which out-cuts some 7-1/4" saws).
Same as the drill: the battery platform is the real long-run cost, so buy the saw that matches the platform you already own. Then blade size — 6-1/2" is the modern cordless standard (lighter, easier overhead and on a ladder, still bevels through 2x stock); 7-1/4" gives full corded-blade depth and deeper bevels for structural or angled 2x work. Then a detail most buyers miss: blade-left vs blade-right. For a right-hander, blade-left gives the better sightline — you see the cut line and the saw's weight sits on the supported side. The old "sidewinders are blade-right" rule is outdated; the DeWalt and Milwaukee here are deliberately blade-left, the budget Ryobi is blade-right. And the honest part: this tool can kick back — bind the blade and it lurches toward you. That's why it rates a higher know-how bar; technique and clamping discipline matter (covered below).
The picks — good, better, best
Picked by Al, the Building Doctor
IUOE Local 39 Stationary Engineer (2001) · 30+ years across hospitality, Class A retail, and senior living. Personal: a 6-1/2" blade-left saw on the same batteries as my drill — light enough for overhead, and I can see the line.
A circular saw is the first tool that can really hurt you if you're careless — kickback is real. Buy a good one, set the blade shallow, support your stock, and respect it. Do that and it's the workhorse of every project.
DeWalt DCS565 (20V MAX XR 6-1/2", brushless)
Compact, brushless, built blade-left for a clear sightline, with an electric brake and a 50° bevel — on the same DeWalt 20V MAX platform as the drill and impact driver we recommend. Light enough for overhead and ladder work, deep enough to bevel 2x stock.
Tradeoff: owners call the plastic lower blade guard a bit flimsy; 6-1/2" gives up a little depth vs a 7-1/4". (Step up to the DeWalt DCS570 7-1/4" on the same platform if you cut 2x at angles.)
Best for: the homeowner who'll actually use it and already owns (or will buy) DeWalt 20V MAX.
Ryobi ONE+ HP 7-1/4" (PBLCS300)
Brushless, a full 7-1/4" blade, on the biggest budget ecosystem (Ryobi ONE+, 300+ tools) — the same budget platform our drill guide points first-timers to. Has a "sightline blower" to keep the cut line clear.
Tradeoff: homeowner/prosumer-grade (not daily-abuse pro), and it's blade-right — a worse sightline for a right-hander; some report a power dip on heavy angle cuts.
Best for: the first-time DIYer already on (or starting) Ryobi ONE+.

Heads up: DeWalt's coverage is a 3-year limited warranty + 1-year free service + 90-day money-back — but it applies only to authorized-seller purchases, and the battery carries a separate, shorter warranty. Same for Milwaukee (5-yr tool) and Ryobi (3-yr). Buy from the official store or a real dealer. How to actually get a claim honored →
6-1/2" or 7-1/4", and which platform?
| Ryobi ONE+ HP 7-1/4" Budget | DeWalt DCS565 6-1/2" The one I'd buy | Milwaukee 2730 6-1/2" Premium | |
|---|---|---|---|
| Platform | Ryobi ONE+ (biggest budget) | DeWalt 20V MAX (popular middle) | Milwaukee M18 (deepest pro) |
| Blade size | 7-1/4" (full depth) | 6-1/2" (lighter) | 6-1/2" (cuts above its size) |
| Sightline | Blade-right | Blade-left | Blade-left |
| Brake | Brushless | Brushless + electric brake | Brushless + electric brake |
| Best for | First saw / occasional | Buy-once homeowner | Renovator / light pro |
The honest answer: the DeWalt DCS565 is the pick for most — light, blade-left, on the popular platform, with the safety of an electric brake. Go Ryobi to get a full 7-1/4" blade for less on the budget platform (just live with the blade-right sightline). Go Milwaukee if you renovate and want pro-grade. The size rule: 6-1/2" for trim, plywood, and overhead work; 7-1/4" if you cut structural 2x at angles. Need furniture-grade straight cuts in sheet goods? That's a track saw (or a circular saw + clamped straightedge / Kreg guide) — the precision step-up, not a replacement.
Honest about the trophies: Fine Homebuilding's 2026 6-1/2" test named Makita best overall and Ridgid best value — DeWalt was tested but didn't win — and Pro Tool Reviews crowns the Milwaukee M18 FUEL 2732 best overall. So why is my verdict the DeWalt DCS565? Platform fit — it shares a battery with the drill I already told you to buy, and for a homeowner that beats the last few percent of cutting speed. I'd rather tell you that straight than pretend it won a trophy it didn't.

Cordless bogs on long rips in wet lumber — corded still wins for all-day production.— trade forum
Representative of owner reviews & trade-forum sentiment — paraphrased and source-typed, not republished.
Owners overwhelmingly favor the 6-1/2" cordless for around-the-house work (lighter, overhead-friendly), and "buy it on your drill's battery" is the most-repeated advice. Blade-left gets specific praise from right-handers for the sightline, and the right blade (24T to rip, 60T for clean plywood) comes up constantly. The honest negatives: budget saws' plastic guards feel flimsy and stick, and corded still wins for all-day production rips in heavy lumber.
How I actually shop for a circular saw (and the blade matters)
I match the saw to my drill's platform, pick 6-1/2" for the lighter weight, and insist on blade-left so I can see the line. Then I spend the saved money on blades, because the blade matters as much as the saw: a 24-tooth rips framing fast but tears plywood; a 60-tooth gives clean sheet-good cuts. A two-blade kit (24T + 60T) covers almost everything.
When I'm standing at the rack, here's the whole checklist:
- Match your drill's battery platform — the real long-run decision.
- Brushless + an electric brake — efficiency and a real safety feature.
- Blade-left (for a right-hander) so you can see the cut; 6-1/2" for most, 7-1/4" for structural 2x.
- The right blade — 24T to rip, 40T combo all-rounder, 60T for clean plywood.
What a circular saw is for (and what it isn't)
- Straight cuts in lumber and sheet goods — decking, plywood breakdown, framing, fencing, shelving.
- Bevel cuts to 45–50° for angled work.
- Not for curves — that's a jigsaw; not for furniture-grade panels — that's a track saw; not for metal — use the right tool/blade (see hacksaw for hand metal cuts and hand saw for wood by hand).
Don't get hurt — kickback and the safety rules
- Kickback is the big one: if the blade binds or pinches, the saw lurches back at you. Prevent it with a sharp blade, no forcing, both hands on the saw, and releasing the trigger the instant it starts to bind.
- Don't pinch the kerf. Support the stock so the offcut falls away and the keeper side stays supported — a board sagging between two sawhorses closes the cut and pinches the blade. The homeowner trick: cut sheet goods on a rigid foam sheet on the ground.
- Set the blade depth shallow — only 1/4–1/2" below the stock. Deeper = more exposed blade and more kickback energy.
- Never defeat the lower guard. Let it self-retract; propping or zip-tying it open is how people get cut.
- Use the right blade, clamp a straightedge for accuracy, and wear your safety glasses and hearing protection.
A word on DeWalt
It's worth knowing the verdict brand. DeWalt was founded in 1924 by Raymond E. DeWalt — the inventor of the radial-arm saw — and is now a brand of Stanley Black & Decker, marking its centennial in 2024. The DCS565 earns its everyday spot not on a single spec but on the thing that matters most to a homeowner: a deep, widely-owned 20V MAX battery platform that shares power with the drill and impact driver we recommend. Buy the platform you'll build on.
FAQ
Cordless or corded for a homeowner?
Cordless — modern brushless saws match corded power for DIY-scale 2x and sheet goods, and the freedom is worth it. Corded still wins for all-day production rips where runtime is the limiter.
6-1/2" or 7-1/4" blade?
6-1/2" for trim, plywood, remodel, and overhead work (lighter, easier to control). 7-1/4" if you cut structural 2x at angles or want full corded-blade depth and a deeper bevel.
What can a circular saw cut?
Straight cuts in lumber and sheet goods — and with the right blade, plywood, OSB, and some plastics or masonry (specialty blades). Not curves (jigsaw) and not fine metal (use a metal-cutting tool/blade).
Is a circular saw safe for a beginner?
Yes, with respect — it's a higher-know-how tool than a drill because of kickback. Learn to support the stock, set the blade depth shallow, clamp a straightedge, never defeat the guard, and keep both hands on the saw.
Blade-left or blade-right — which is better?
For a right-hander, blade-left gives the better sightline (you see the cut line and the weight sits on the keeper side). The DeWalt and Milwaukee picks are blade-left; the budget Ryobi is blade-right.
What's the difference between a sidewinder and a worm drive?
A sidewinder has the motor parallel to the blade — lighter, faster, the homeowner default. A worm drive is geared at 90° — heavier, more torque, traditionally blade-left (pro framing). Most cordless saws are sidewinders.
Do I need a track saw?
Only if you regularly cut expensive sheet goods to furniture-grade precision (roughly 1/32" vs 1/16"). For most homeowners, a circular saw plus a clamped straightedge or a Kreg guide is plenty.
What blade should I run?
24-tooth for fast framing rips, 40-tooth combo as an all-rounder, and 60-tooth for clean plywood and finish cuts. A 24T + 60T two-blade kit covers most DIYers.
Should it match my drill's battery?
Yes — buy the saw on the same platform as your drill so the battery you already own clicks right in. That's the single most practical decision in cordless power tools.
The bottom line
One saw, one answer: the DeWalt DCS565 — brushless, blade-left, electric brake, on the platform you likely already own. Cheapest full-size way in? The Ryobi ONE+ HP 7-1/4". Pro-grade? The Milwaukee M18 FUEL. Whatever you buy: match your drill's platform, pick the blade size for your work, run the right blade, and respect kickback — set the blade shallow, support the stock, and never defeat the guard.
